I am trying to plan out my next tank and need some help. I am going to get a 180 gallon tank with a wet/dry filter. The filter has two outputs that each go to a pump and back to independent pre filters in the tank. I want to put a CO2 reactor on one of the outputs from the filter that returns the water to the tank. The returns have 3/4 inch tubing so I will have to build my own reactor but that won't be a problem. My question is the pump flows at 960 gph, is this going to be too much water flowing through the reactor? The reactor will resemble an aquamedic 1000 reactor ( http/aquarium-supply.biz/products/aquamedic_reactor.jpg ) This reactor recommends a min flow of 250 gph but also mentions a bypass if the flow is too high but does not give a max flow rate.
